She bought 54 child tickets and 19 adult tickets.
Step-by-step explanation:
No. of tickets purchased = 73
Cost of tickets = $771
Cost of one child ticket = $9
Cost of one adult ticket = $15
Let,
Child ticket = x
Adult ticket = y
According to given statement;
x+y=73 Eqn 1
9x+15y=771 Eqn 2
Multiplying Eqn 1 by 9;

Subtracting Eqn 3 from Eqn 2;

Dividing both sides by 6;

Putting y=19 in Eqn 1

She bought 54 child tickets and 19 adult tickets.

Answer:
c = 2
Step-by-step explanation:
Since 16 is over the variable c, first multiply both sides by c so the variable is not in the denominator of the fraction.
16/c(c) = 8(c)
16 = 8c Next, divide both sides by 8 to solve for c.
c = 2
The pattern goes like this...
(1st letter from the beginning),(1st letter from the end),(2nd letter from the beginning),(2nd letter from the end), etc.
So the next letter in the pattern should be W.
Answer:
length of segment AB is 13
OR
AB = 13
Step-by-step explanation:
Use the Pythagorean Theorem with c being the length of segment AB.
a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169 = c ^2 (square root both sides to get c by itself)
13 = c
